Key features:Multiple installations and commissioning optionsSet up and control through the App via BluetoothContinuous or intermittent runningSilent hours scheduling and purge mode functions3 speed settings5-year guaranteeFully flexible installation and app controlTake control of your home ventilation with the Svara extractor fan from Vent-Axia. It gives you complete control over your indoor air filtration through an intuitive app designed for total fan running flexibility. This is not only great for installers but homeowners too, meaning that any settings can be easily changed without the need for an installer to inspect the unit. Simply log on to the App and change the setting yourself.Silent operationExtractor fans historically haven’t been known for their silent operation but the Svara changes this with its ultra-quiet blades that operate at just 17dB(A) on low trickle. That is seriously quiet for something that’s effectively changing the airflow around your home.Multi-room functionBecause the Svara is so powerful it’s perfectly fine to be used in either a bathroom or a kitchen, and can be set to operate continuously or intermittently. This can of course be set using the Bluetooth-enabled app.Light sensorAs standard, these extractor fans are set for continuous operation at low speed, with an adjustable timer that can be triggered via a switch or light sensor. The light sensor recognises that someone is in the room through light movement or shadows, with a delay-on feature for those quick trips to the bathroom at night. Humidity sensorSvara features a humidistat which reacts to sharp increases in humidity, for example, someone taking a shower or having a hot bath. If set to continuous running the fan will run at 30l/s until levels have returned to normal, then return to 10l/s. Ambient changes in humidity won’t trigger the sensor and it is possible to change the sensitivity via the app.Silent scheduling and automatic cyclesExtractor fans on full power can be noisy and the Svara is no exception, you can, however, set silent hours stopping the fan from boosting power at certain times like overnight. You can also set a holiday airing mode so the Svara operates a purge function every 12 hours, for either 30, 60 or 90 minutes. If the light sensor picks up motion this won’t be activated though.Additional information:Removable impeller for easier cleaning and replacement with a wipe-clean fasciaIntelligent light sensor with overrun timer - allows replacement of a basic model fanIP44 RatedDC type motorSuitable for ceiling, panel or wall mountingMinimal 17 dB(A) noise levelsLow running costs at just 4W
